ABSTRACT

Described are branched ketones defined according to the generic structure: ##STR1## wherein R 4  &#39; represents C 1  -C 4  lower alkyl; wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines represents carbon-carbon single bonds. Also described are organoleptic uses of these branched ketones in augmenting or enhancing the aroma or taste of consumable materials such as perfume compositions, colognes, perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents; cosmetic powders; hair preparations; fabric softener compositions and dryer-added fabric softener articles), foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, smoking tobaccos and smoking tobacco articles as well as processes for preparing such branched ketones by reacting dimers of isoamylene with acyl halides or acyl anhydrides or mixed acyl anhydrides.

This application is a continuation-in-part of application for U.S. Pat. Ser. No. 184,132 filed on Sept. 4, 1980, now U.S. Pat. No. 4,321,255.

BACKGROUND OF THE INVENTION

The present invention relates to branched ketones of the genus of compounds having the structure: ##STR2## wherein R₄ ' represents C₁ -C₄ lower alkyl; wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines represents carbon-carbon single bonds, produced by the novel process of our invention, and to novel compositions using one or more of such branched ketones to augment or enhance the flavor and/or aroma of consumable materials, or impart flavor and/or aroma to consumable materials.

There has been considerable work performed relating to substances which can be used to impart (modify, augment or enhance) flavors and fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural materials, some of which may be in short supply, and to provide more uniform properties in the finished product.

Woody, citrus, floral, ionone-like, incense-like, oriental, grapefruit-like, piney, fruity and rosin-like aromas with woody, citrusy, floral, ionone-like, oriental, grapefruit-like, piney, fruity and rosin-like tastes with bitter undertones are particularly desirable for many uses in foodstuff flavors, chewing gum flavors, toothpaste flavors, medicinal products flavors and chewing tobacco flavors.

Sweet, woody, oriental-like, camphoraceous, fruity and spicey aromas prior to smoking and woody, peppery and oriental-like aromas with natural tobacco nuances on smoking in the main-stream and in the side-stream are desirable in smoking tobaccos, smoking tobacco articles and in smoking tobacco flavoring compositions.

Fruity, warm, woody, amber, rum/cognac-like, sandalwood-like, sweet, floral, rich woody, vetiver-like, aromas with patchouli top-notes and minty undertones, are highly desirable in several types of perfume compositions, perfumed articles and colognes.

Unsaturated ketones including unsaturated branched aliphatic, acyclic ketones are well known for use in augmenting or enhancing the aroma and/or taste of consumable materials. Thus, Arctander, "Perfume & Flavor Chemicals (Aroma Chemicals)", published 1969, discloses at monograph No. 472, the use of butylidene acetone having the structure: ##STR3## Arctander states that butylidene acetone has a powerful, grassy, green, pungent odor and a rather poor tenacity. At monograph 2427, Vol. 2, Arctander states that Octylidene acetone having the structure: ##STR4## is useful in Jasmin compositions as a modifier for Amylcinnamic aldehyde, or in Gardenia and other heavy floral perfumes, where herbaceous-fruity notes are desirable and compatible with the fragrance picture.

U.S. Pat. No. 2,315,046 discloses the use as ingredients in perfumery of certain acylated olefins, which olefins have structures such as: ##STR5##

These materials are prepared interalia from commercial diisobutylene according to the reaction: ##STR6## wherein n is 3 or more, and R represents a hydrocarbon radical. Branched unsaturated alpha-beta ketones were known prior to that, for example, in U.S. Pat. No. 2,246,032, issued on June 17, 1941, disclosing compounds having the generic structure: ##STR7## wherein R₁ -R₇ may be any member of the group consisting of hydrogen, aliphatic and cyclo paraffinic.

Also, claimed in U.S. Pat. No. 2,315,046 are compounds having the structures: ##STR8##

In addition, U.S. Pat. No. 2,463,742 discloses the reaction: ##STR9##

U.S. Pat. No. 3,453,317, issued on July 1, 1969, discloses certain gamma, delta unsaturated ketones as odorants for perfumery purposes at Column 4, line 33 including the group of ketones having the structure: ##STR10## wherein R₁ -R₅ are various hydrocarbon radicals.

U.S. Pat. No. 2,870,210, discloses as having aromas such as fruity, "reminiscent of apple juice" the compound 6,8-dimethyl-5-nonene-2-one having the structure: ##STR11## as well as 6,10-dimethyl-5-undecane-2-one having the structure: ##STR12##

Nothing in the prior art specifically discloses the genus of compounds having the structure: ##STR13## wherein R₄ ' represents C₁ -C₃ lower alkyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond. And nothing in the prior art discloses the generic process: ##STR14## wherein R₁ ', R₂ ' and R₃ ' are the same or different and each represents C₁ -C₃ lower alkyl; wherein R₄ ' is as defined above and wherein X is chloro or bromo. Indeed, the compounds and processes of our invention give rise to unexpected, unobvious and advantageous utilities insofar as organoleptic uses are concerned.

As discussed in Application for U.S. Pat. No. 160,788 filed on June 19, 1980 and incorporated by reference herein, it has been recently ascertained that isoamylene may be dimerized to provide an inexpensive, highly useful, hydrocarbon material having commercially useful and commercially significant organoleptic properties in the field of perfumery. Thus, when isoamylene is dimerized, the following reaction takes place: ##STR34## yielding the products having the structures: ##STR35##

The compounds having the structures: ##STR36## depolymerize to form t-amylene, which, in turn, re-polymerizes to form the compound having the structure: ##STR37##

Thus, the dimerization product of diisoamylene is further reacted to form other significantly useful perfumery products, food flavor products and other organoleptically useful materials by means of acylation with either an acyl halide, or an acylanhydride according to the generic reaction: ##STR38## wherein R₄ ' represents C₁ -C₄ alkyl; wherein R₁ ', R₂ ' and R₃ ' are the same or different and each represents C₁ -C₄ alkyl; and wherein X is halogen selected from the group consisting of chloro or bromo; and wherein in each of the molecules, one of the dashed lines represents a carbon-carbon double bond and the other dashed lines represent carbon-carbon single bonds.

Thus, it has now been discovered that novel solid and liquid foodstuff, chewing gum, medicinal products, toothpastes and chewing tobacco compositions, and flavoring compositions therefor having woody, citrus, floral, ionone-like, incense-like, oriental, grapefruit-like, piney, fruity and rosin-like aroma nuances as well as woody, citrus, floral, ionone-like, oriental, grapefruit-like, piney, fruity and rosin-like taste nuances with bitter undertones; as well as novel tobacco and tobacco flavoring compositions having sweet, woody, oriental, camphoraceous, fruity and spicey aroma and taste nuances prior to smoking, and woody, peppery and oriental-like aroma and taste nuances on smoking, in both the mainstream and the sidestream; as well as novel perfume compositions, colognes and perfumed articles (e.g. solid or liquid anionic, cationic, nonionic and zwitterionic detergents; cosmetic powders; hair preparations; fabric softener compositions; and dryer-added fabric softener articles) having an intense and long-lasting sweet, rich, warm woody, fruity, amber, rum/cognac-like, sandalwood, sweet floral and vetiver-like aroma nuances with patchouli top-notes as well as minty undertones, may be provided by the utilization of one or more branched acyclic, unsaturated ketone derivatives, defined according to the generic structure: ##STR39## wherein R₄ ' represents C₁ -C₄ lower alkyl; wherein in each molecule, one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represent carbon-carbon single bonds.

Unless otherwise specified, representation herein of carbon-carbon double bonds are intended to indicate a "cis" isomer, a "trans" isomer, or a mixture of "cis" and "trans" isomers with respect to that carbon-carbon double bond in the event that the carbon-carbon double bond is susceptible of such "cis-trans" isomerism.

The novel branched, unsaturated ketones of our invention may be prepared by first preparing diisoamylene as by dimerizing isoamylene according to the reaction: ##STR40## The resulting diisoamylene material thus produced, is used "as is" in the subsequent acylation reaction. Thus, for example, the subsequent acylation reaction may be carried out on the mixture of diisoamylene molecules according to the reaction: ##STR41## wherein the acylation is carried out using an organic acid anhydride or a mixed anhydride, or an acyl halide. In the foregoing reaction, R₁ ', R₂ ' and R₃ ' represent the same or different C₁ -C₄ alkyl, methyl, ethyl, n-propyl, i-propyl, n-butyl or i-butyl; and X represents chloro or bromo; and one of the dashed lines in the reaction product represents a carbon-carbon double bond, and each of the other of the dashed lines represent carbon-carbon single bonds. This reaction is carried out in the presence of an acid catalyst, which may be either a Lewis acid or a mineral acid. When using Lewis acids, such as boron trifluoride etherate, zinc chloride, aluminum chloride, zinc bromide, diethyl aluminum chloride, ethyl aluminum dichloride, stannic chloride or zinc bromide, the temperature of reaction may vary between -80° C. and +80° C. with a preferred reaction temperature of between -80° C. and 50° C. When using a mineral acid, such as, methane sulfonic acid, sulfuric acid, phosphoric acid, polyphosphoric acid, or a mixture of methane sulfonic acid and phosphorous pendoxide, the temperature of reaction may vary between 25° C. and 150° C. with a preferred reaction temperature of between 40° C. and 110° C.

The mole ratio of dimer of isoamylene:acylating agent (e.g., acyl anhydride) may vary between 1:1.1 and 2:1.0, with a preferable mole ratio of diisoamylene:dimer:acylating agent being about 1:0.7. Various acyl anhydrides or acyl halides may be used, for example:

Acetic anhydride

Propionic anhydride

n-Butyric anhydride

i-Butyric anhydride

Acetic propionic anhydride

Acetic n-butyric anhydride

Acetic i-butyric anhydride

Propionic i-butyric anhydride

Propionic n-butyric anhydride

Acetyl chloride

Iso-valeryl chloride

Iso-butyryl chloride

n-Propionyl chloride

n-Propionyl bromide

The concentration of catalysts in the reaction mass may vary from 2.5 weight percent to 150 weight percent with a preferred concentration (Lewis acid or mineral acid) being between 5 and 10% by weight of the reaction mass.

Although an inert solvent may be used in the reaction mass (e.g., benzene, toluene, xylene, dichloromethane, 1,2-dichlorobenzene and mixtures of methylene dichloride and pyridene) with certain catalysts it is preferred that no solvent be used and with other catalysts it is preferred that specific solvents be used in order to achieve specific effects. Thus, when using acetic anhydride in the presence of a boron trifluoride etherate catalyst, it is preferred that no additional solvent be used. On the other hand, when using iso-valeryl chloride as a reactant it is preferred that the solvent used is a mixture of methylene dichloride and pyridene when using a stannic chloride catalyst.

Although pressures greater than or less than atmospheric pressure may be used, no specific advantages are seen in using higher or lower pressures insofar as conversion, yield or time of reaction is concerned.

Accordingly, it is most preferred to use atmospheric pressure as a reaction condition.

Interestingly, when iso-valeryl chloride is used as a reactant with the diisoamylene reaction product, at a temperature of -78° C. using a stannic chloride catalyst and a methylene dichloride and pyridine solvent, substantially pure isomer having the structure: ##STR42## is formed and this effect in it of itself is surprising and unexpected.

When the unsaturated branched-chain ketone derivatives of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with each of the said unsaturated branched-chain ketone derivatives in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith.

As used herein in regard to flavors, the terms "alter", "modify" and "augment" in their various forms means "supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste".

The term "enhance" is used herein to intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, "enhancement" of a flavor or aroma means that the "enhancement" of a flavor or aroma means that the enhancement agent does not add any additional flavor note.

As used herein, the term "foodstuff" includes both solid and liquid ingestible materials which usually do, but need not, have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks and the like.

As used herein, the term "medicinal product" includes both solids and liquids which are ingestible non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.

The term "chewing gum" is intended to mean a composition which comprises a substantially water-insoluble, chewable plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain cosmetible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therewith may be plasticizers or softening agents, e.g., glycerine; and a flavoring composition which incorporates one of the unsaturated branched-chain ketones of our invention, and in addition, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.

Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be "ingestibly" acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterized as flavoring adjuvants or vehicles comprising broadly stabilizers, thickeners, surface active agents, conditioners, other flavorants and flavor intensifiers.

Stabilizer compounds include preservatives, e.g., sodium chloride; antioxidants, e.g., calcium and sodium ascorbate, ascorbic acid, butylated hydroxyanisole (mixture of 2- and 3-tertiary-butyl-4-hydroxyanisole), butylated hydroxytoluene (2,6-di-tertiary-butyl-4-methylphenol), propyl gallate and the like and sequestrants, e.g., citric acid.

Thickener compounds include carriers, binders, protective colloids, suspending agents, emulsifiers and the like, e.g., agar agar, carrageenan, cellulose and cellulose derivatives such as carboxymethyl cellulose and methyl cellulose; natural and synthetic gums such as gum arabic, gum tragacanth; gelatin, proteinaceous materials; lipids; carbohydrates; starches, pectins, and emulsifiers, e.g., mono and diglycerides of fatty acids, skim milk powder, hexoses, pentoses, disaccharides, e.g., sucrose, corn syrup and the like.

Surface active agents include emulsifying agents, e.g., fatty acids such as capric acid, caprylic acid, palmitic acid, myristic acid and the like, mono and diglycerides of fatty acids, lecithin, defoaming and flavor-dispersing agents such as sorbitan monostearate, potassium stearate, hydrogenated tallow alcohol and the like.

Conditioners include compounds such as bleaching and maturing agents, e.g., benzoyl peroxide, calcium peroxide, hydrogen peroxide and the like; starch modifiers such as peracetic acid, sodium chlorite, sodium hypochlorite, propylene oxide, succinic anhydride and the like, buffers and neutralizing agents, e.g., sodium acetate, ammonium bicarbonate, ammonium phosphate, citric acid, lactic acid, vinegar and the like; colorants, e.g., carminic acid, cochineal, tumeric and curcuma and the like; firming agents such as aluminum sodium sulfate, calcium chloride and calcium gluconate; texturizers, anti-caking agents, e.g., aluminum calcium sulfate and tribasic calcium phosphate; enzymes; yeast foods, e.g. calcium lactate and calcium sulfate; nutrient supplements, e.g., iron salts such as ferric phosphate, ferrous gluconate and the like, riboflavin, vitamins, zinc sources such as zinc chloride, zinc sulfate and the like.

Other flavorants and flavor intensifiers include aldehydes, esters, natural oils, alcohols, sulfides, ketones, lactones, carboxylic acids and hydrocarbons such as heliotropin, terpineol-4, benzaldehyde, anisaldehyde, phenyl acetaldehyde, benzyl formate, benzyl acetate, cis-3-hexenyl benzoate, methyl hexanoate, hexanal, eucalyptol, eugenol, acetaldehyde, ethyl acetate, ethyl butyrate, turpentine gum oil, limonene, gum camphor, isobornyl acetate, borneol, cinnamic aldehyde, cuminic aldehyde, furfural, methyl cinnamate, cassia oil, vanillin, maltol, parahydroxybenzyl acetone, dimethyl sulfide, alpha-ionone, acetic acid, isobutyl acetate, acetone, butyric acid, formic acid, valeric acid, amyl acetate, amyl butyrate, anethol, benzyl salicylate, diacetyl, di-methyl anthranilate, ethyl methylphenylglycidate, ethyl succinate, ethyl valerate, geraniol, cis-3-hexen-1-ol, 2-hexenyl acetate, 2-hexenyl butyrate, 4-(p-hydroxyphenyl)-2-butanone, beta-ionone, isobutyl cinnamate, jasmine, lemon essential oil, methyl butyrate, methyl caproate, methyl disulfide, methyl p-naphthyl ketone, orris butter, rose absolute, terpenyl acetate, gammaundecalactone, vanilla and alcohol.

The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, should, in any event, (i) be organoleptically compatible with the unsaturated branched-chain ketone derivatives of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be nonreactive with the unsaturated branched-chain ketone derivatives of our invention and (iii) be capable of providing an environment in which the unsaturated branched-chain ketone derivatives can be dispersed or admixed to provide homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g. simulated foodstuffs, ingredients capable of provuding normally solid compositions should be selected such as various cellulose derivatives.

As will be appreciated by those skilled in the art, the amount of unsaturated branched-chain ketones employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quanities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma. The primary requirement is that the amount selected to be effective, i.e., sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum, per se, medicinal product per se, toothpaste per se, or flavoring composition.

The use of insufficient quantities of unsaturated branched-chain ketones will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and, in extreme cases, may disrupt the flavor-aroma balance, thus proving self defeating. Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.

Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of unsaturated branched-chain ketones ranging from a small, but effective amount, 0.05 parts per million up to about 100 parts per million based on total composition are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended, since they fail to prove commensurate enhancement of organoleptic properties. In those instances, wherein the unsaturated branched-chain ketones are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective unsaturated branched-chain ketones concentration in the foodstuff product.

Food flavoring compositions prepared in accordance with the present invention preferably contain the unsaturated branched-chain ketones in concentrations ranging from about 0.1% up to about 15% by weight based on the total weight of the said flavoring composition.

The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency. homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the unsaturated branched-chain ketones with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Pre-prepared flavor mixes in powder form, e.g., a fruit-flavored powder mix are obtained by mixing the dried solid components, e.g., starch, sugar and the like and the unsaturated branched-chain ketones in a dry blender until the requisite degree of uniformity is achieved.

An additional aspect of our invention provides an organoleptically improved smoking tobacco product and additives therefor, as well as methods of making the same which overcome problems heretofore encountered in which specific desired sweet, woody, oriental, spicey and fruity flavor characteristics of natural "Turkish-like" tobacco (prior to smoking and, on smoking, in the mainstream and in the sidestream) are created or enhanced or modified or augmented and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend.

This invention further provides improved tobacco additives and methods whereby various desirable natural aromatic tobacco flavoring characteristics with sweet, woody, oriental type, camphoraceous, fruity and spicey, as well as peppery taste and aroma nuances may be imparted to smoking tobacco products, and may be readily varied and controlled to produce the desired uniform flavoring characteristics.

In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more unsaturated branched-chain ketones of our invention.

In addition to the unsaturated branched-chain ketones of our invention other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in mixture with the unsaturated branched-chain ketones as follows:

An aroma and flavoring concentrate containing one or more unsaturated branched-chain ketones of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of natural and/or sweet notes and/or woody notes and/or oriental-like notes and/or camphoraceous notes and/or fruity notes and/or spicey notes and/or peppery notes, we have found that satisfactory results are obtained in the proportion by weight of the sum total of unsaturated branched-chain ketone derivative(s) to smoking tobacco material is between 50 ppm and 1,500 ppm (0.015%-0.15%). We have further found that satisfactory results are obtained if the proportion by weight of the sum total of unsaturated branched-chain ketone derivatives used to flavoring material is between 1,500 and 15,000 ppm (0.15%-1.5%).

Any convenient method for incorporating the unsaturated branched-chain ketone derivative(s) into the tobacco product may be employed. Thus, the unsaturated branched-chain ketone derivative(s) taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, diethyl ether and/or volative organic solvents and the resulting solution may either be spread on the cured, cased and blended tobacco material or the tobacco material may be dipped into such solution. Under certain circumstances, a solution of the unsaturated branched-chain ketone derivative(s) taken alone or taken further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying or dipping, or coating.

Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have the unsaturated branched-chain ketone derivative(s) in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.

In accordance with one specific example of our invention, an aged, cured and shredded domestic burley tobacco is sprayed with a 20% ethyl alcohol solution of the compound having the structure: ##STR51## in an amount to provide a tobacco composition containing 800 ppm by weight of said compound on a dry basis. Thereafter, the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarette, when treated as indicated has a desired and pleasing aroma which is defined as woody and peppery with oriental and fruity and spicey undertones detectable in the main and the sidestreams when the cigarette is smoked. This aroma is described as being sweeter, more aromatic, more Turkish tobacco-like and having sweet, fruity, peppery, woody and oriental nuances which cause the burley tobacco to equate Turkish-like.

While our invention is particularly useful in the manufacture of smoking tobacco, such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products, formed from the sheeted tobacco dust or fines may also be used. Likewise, the unsaturated branched-chain ketone derivative(s) of our invention can be incorporated with materials such as filter tip materials (e.g., cellulose acetate filters wherein sweet, woody, oriental, spicey and/or fruity effects are desired), seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the unsaturated branched-chain ketone derivative(s) can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughout this specification is meant any composition intended for human consumption by smoking or otherwise, whether composed of tobacco of tobacco plant parts or substitute materials or both.

The unsaturated branched-chain ketone derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters, lactones or cyclic ester, synthetic essential oils and natural essential oils, may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the woody, sandalwood-like, patchouli-like, amber and/or vetiver and/or fruity fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling fresh smelling materials.

In perfume composition, it is the individual components which contribute to their particular olfactory characteristics, however the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the unsaturated branched-chain ketone derivative(s) of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of unsaturated branched-chain ketone derivative(s) of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of unsaturated branched-chain ketone derivative(s) or even less (e.g., 0.005%) can be used to impart a sweet, rich, warm woody, fruity, amber, rum/cognac-like, sandalwood-like, sweet, floral, long-lasting vetiver-like aromas with patchouli top-notes and minty undertones to soaps, cosmetics, detergents (including anionic, nonionic and cationic detergents) or other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The unsaturated branched-chain ketone derivative(s) of our invention are useful (taken alone or together with other ingredients in perfume compositions) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations, such as lacquers, brillantines, pomades and shampoos; cosmetic preparations, such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders and the like. As little as 1% of the unsaturated branched-chain ketone derivative(s) will suffice to impart an intense piney note to woody perfume formulations. Generally, no more than 3% of the unsaturated branched-chain ketone derivative(s) based on the ultimate end product, is required in the perfume composition.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle, or carrier for the unsaturated branched-chain ketone derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, a non-toxic glycol, or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic), or components for encapsulating the composition (such as gelatin).

It will thus be apparent that the unsaturated branched-chain ketone derivative(s) of our invention can be utilized to alter, modify or enhance sensory properties, particularly organoleptic properties, such as flavor(s) and/or fragrance(s) of a wide variety of consumable materials.

The following Example A sets forth procedures for preparing precursors of the compounds of our invention, the unsaturated branched-chain ketones.

The following Examples I-VIII and XXXIX set forth procedures for preparing the unsaturated branched-chain ketones of our invention.

The remainder of the examples set forth the uses of the unsaturated branched-chain ketones of our invention for their organoleptic properties.

It will be understood that these examples are illustrative and that the invention is to be considered restricted thereto, only as indicated in the appended claims.

All parts and percentages given herein are by weight, unless otherwise specified.

Reaction: ##STR60## wherein in each of the structures containing dashed lines, these structures represent mixtures of molecules wherein in each of the molecules, one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds.

Into a 5-liter reaction flask equipped with reflux condenser, addition funnel, thermometer, "Thermowatch", heating mantle and nitrogen purge accessory is placed 1000 g (7.45 moles) of propionic anhydride, 94% and 91.4 ml (0.745 moles) of boron trifluoride etherate. The resulting mixture is heated to 65° C. Over a twenty-five minute period, 1,501 ml (7.45 moles) of the diisoamylene prepared according to the illustration of Example A is added while maintaining the reaction mass at 65°-70° C. The reaction mass is then stirred for a period of thirty minutes at 65° C. whereupon it is cooled and poured into a 3 liter separatory funnel. 75 ml water is then added, followed by 75 ml 50% aqueous sodium hydroxide and another 25 ml water. The reaction mass is then poured into a 4 liter beaker and cooled to room temperature using a dry ice-isopropyl alcohol bath. The reaction mass is then added to a 5-liter separatory funnel and the lower aqueous layer is removed. The upper organic phase is washed with 500 cc of saturated sodium chloride. The organic phase is then washed with 500 cc 5% sodium hydroxide followed by 500 cc saturated sodium chloride, followed by 500 cc of 5% sodium hydroxide. The pH of the oil is now in a range of 6-7. The oil is then again washed with 500 cc saturated sodium chloride.

The aqueous phase is extracted with 400 ml diethyl ether. The resulting material is then distilled on a two inch splash column yielding the following fractions:

EXAMPLE XVII

Four drops of one of the substances set forth in Table VIII below is added to two grams of Aromox® DMC-W to produce a clear premix. The clear premix is added to 200 grams of CLOROX® with stirring resulting in a clear stable, single phase solution. Sufficient 1 M aqueous NaOH is added to bring the pH of the mixture up to 12.8. The solution remains substantially stable at 120° F. for a period of seven days. When the 5% aqueous sodium hypochlorite solution is used as a laundry bleach, the resulting laundry, on dry-out in an atmosphere of 65% relative humidity yields substantially no characteristic "hypochlorite" odor, but does have a faint pleasant aroma as set forth in Table VIII below. Furthermore, no such characteristic "hypochlorite" aroma is retained on the hands of the individual handling such laundry in both the wet and the dry states:

When the 5% aqueous sodium hypochlorite solution is used as a laundry bleach, the resulting laundry on dry-out, in an atmosphere of 65% relative humidity, yields substantially no characteristic "hypochlorite" odor, but does have a faint, pleaseant aroma as set forth in Table IX below. Furthermore, no such characteristic "hypochlorite" aroma is retained on the hands of the individual handling such laundry in both the wet and the dry states:

EXAMPLE XIX

Two grams of Aromox® DMMC-W is admixed with eight drops of one of the substances set forth in Table X below. The premix is then added with stirring to 200 grams of a 7% aqueous solution of lithium hypochlorite. Sufficient 3 M aqueous LiOH is added to bring the pH of the solution to 13.4.

EXAMPLE XXII

Four drops of one of the substances set forth in Table XIII below is added to 1.5 grams of Aromox® NCMDW to produce a clear premix. The clear premix is added to 200 grams of CLOROX® with stirring resulting in a clear stable single phase solution. Sufficient 1 M aqueous NaOH is added to bring the pH of the mixture up to 12.8. The solution remains substantially stable at 120° F. for a period of 7 days. When the 5% aqueous sodium hypochlorite solution is used as a laundry bleach, the resulting laundry on dry-out in an atmosphere of 65% relative humidity yields substantially no characteristic "hypochlorite" odor but does have a faint pleasant warm, long-lasting aroma as set forth in Table XIII below. Furthermore, no such characteristic "hypochlorite" aroma is retained on the hands of the individual handling such laundry in both the wet and the dry states.

EXAMPLE XXIV

Four drops of one of the substances as set forth in Table XV below are added to 1 gram of n-dodecyl dimethyl amine oxide to produce a clear premix. The clear premix is added to 200 grams of CLOROX® with stirring resulting in a clear, stable single phase solution. Sufficient 1 M aqueous NaOH is added to bring the pH of the mixture up to 12.8. The solution remains substantially stable at 120° F. for a period of 7 days. When the 5% aqueous sodium hypochlorite solution is used as a laundry bleach, the resulting laundry on dry-out in an atmosphere of 65% relative humidity yields substantially no characteristic "hypochlorite aroma, but does have a warm, pleasant, long-lasting aroma as set forth in Table XV below. Furthermore, no such characteristic "hypochlorite" aroma is retained on the hands of the individual handling such laundry in both the wet and the dry states.

EXAMPLE XXV

One gram of n-tridecyl dimethyl amine oxide is admixed with eight drops of one of the substances as set forth in Table XVI below. This premix is then added with stirring to 200 grams of a 7% aqueous solution of lithium hypochlorite. Sufficient 3 M aqueous LiOH is added to bring the pH of the solution to 13.4. The mixture is then heated to 120° F. and maintained at that temperature with stirring for a period of one week. The resulting solution remains clear in a single phase. When used as a laundry bleach, the resulting bleached laundry on dry-out in an atmosphere of 50% relative humidity retains a warm, fresh aroma described in Table XVI below; whereas without the use of one of the substances of Table XVI below, the bleached laundry has a faint characteristic disagreeable "hypochlorite" aroma.

The above formulation is split into two portions. To the first portion is added, at the rate of 1%, the n-butyryl diisoamylene derivative mixture prepared according to Example III, defined according to the structure: ##STR195## wherein in each of the molecules, one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond. The second portion contains nothing additional added thereto. Both formulations, with and without said n-butyryl diisoamylene derivative prepared according to Example III are combined with water at the rate of 100 ppm. The flavor with the n-butyryl diisoamylene derivative mixture, prepared according to Example II has a more winey, fruity, piney character and is closely similar to the flavor of wild blueberries. It is therefor preferred to the basic blueberry formulation which does not contain said n-butyryl diisoamylene derivative.

EXAMPLE XXX TOBACCO FILTER

Into a 20 mm cellulose acetate filter is added: the i-butyryl diisoamylene derivative mixture prepared according to Example IV defined according to the generic structure: ##STR196## wherein in each of the molecules, one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond. At the rate of 1000 ppm (10 micro liter of a 10% solution of said isobutyryl diisoamylene derivative is added to the filter). The filter is then attached to a full flavor cigarette on the market, e.g. (1) Marlboro®, (2) Winston® or (3) Viceroy®, as well as on a Kentucky 1A3 reference cigarette (produced by the University of Kentucky, at Lexington, Kentucky) yielding the following results:

1. Both cigarettes containing the isobutyryl diisoamylene derivative when compared to a cigarette having a filter without said isobutyryl diisoamylene derivative, give rise to a sweet, woody, oriental-like and peppery aroma on smoking, with a pleasant woody, effect and rather noticeable reduced harshness.

2. Both cigarettes containing said isobutyryl diisoamylene derivative mixture, have a lesser degree of "hotness" and give rise to a "Turkish" taste on smoking.

The flavor formulation is divided into two portions. 40 Parts per million of isobutyryl diisoamylene derivative mixture prepared according to Example IV is added to the first portion and nothing is added to the second portion. A definite aroma improvement, more natural grapefruit juice aroma and taste as well as pleasant sour effect, and generally improved taste is created as a result of the addition of the isobutyryl diisoamylene derivative mixture prepared according to Example IV. In general, the isobutyryl diisoamylene derivative mixture prepared according to Example IV supplies a natural grapefruit juice note to this grapefruit flavor.

EXAMPLE XXXII A. POWDER FLAVOR COMPOSITION

20 Grams of the flavor composition of Example XXIX is emulsified in a solution containing 300 gm gum acacia and 700 gm water. The emulsion is spray-dried with a Bowen Lab Model Drier utilizing 260 c.f.m. of air with an inlet temperature of 500° F., an outlet temperature of 200° F. and a wheel speed of 50,000 rpm.

The Cab-O-Sil is dispersed in the liquid blueberry flavor composition of Example XXIX with vigorous stirring, thereby resulting in a viscous liquid. 71 Parts by weight of the powder flavor composition of Part A, supra, is then blended into the said viscous liquid, with stirring at 25° C. for a period of 30 minutes resulting in a dry, free flowing sustained release flavor powder.

EXAMPLE XXXIII

10 Parts by weight of b 50 Bloom pigskin gelatin is added to 90 parts by weight of water at a temperature of 150° F. The mixtures is agitated until the gelatin is completely dissolved and the solution is cooled to 120° F. 20 Parts by weight of the liquid flavor composition of Example XXIX is added to the solution which is then homogenized to form an emulsion having particle size typically in the range of 2-5 microns. This material is kept at 120° F. under which conditions the gelatin will not jell.

Coascervation is induced by adding, slowly and uniformly 40 parts by weight of a 20% aqueous solution of sodium sulphate. During coascervation the gelatin molecules are deposited uniformly about each oil droplet as a nucleus.

Gelation is effected by pouring the heated coascervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulphate at 65° F. The resulting jelled coascervate may be filtered and washed with water at temperatures below the melting point of gelatin, to remove the salt.

Hardening of the filtered cake, in this example, is effected by washing with 200 parts by weight of 37% solution of formaldehyde in water. The cake is then washed to remove residual formaldehyde.

EXAMPLE XXXIV CHEWING GUM

100 Parts by weight of chicle are mixed with 4 parts by weight of the flavor prepared in accordance with Example XXXII. 300 Parts of sucrose and 100 parts of corn syrup are added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Co.

The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long lasting blueberry flavor.

EXAMPLE XXXV CHEWING GUM

100 Parts by weight of chicle are mixed with 18 parts by weight of the flavor prepared in accordance with Example XXXIII. 300 Parts of sucrose and 100 parts of corn syrup are then added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkings Co.

The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long lasting blueberry flavor.

EXAMPLE XXXIX

Reaction: ##STR197##

Into a 250 ml reaction flask equipped with stirrer, addition funnel, thermomether, condenser and dry ice/acetone bath is placed 20.0 grams (0.077 moles) of stannic chloride and 40 ml of methylene dichloride. 10.0 grams (0.083 moles) of isovaleryl chloride dissolved in 40 ml methylene chloride is added dropwise under a nitrogen atmosphere at room temperature with stirring over a period of 10 minutes. The reaction mass is chilled to -73° C. and 14.0 grams (0.1 moles) of diisoamylene prepared according to Example I, dissolve in 40 ml methylene dichloride is added over a period of 1.5 hours. The reaction temperature is set between -76° and -70° C. during addition. The reaction mass is stirred for a period of 0.5 hours at -73° C. 30 ml pyridine is then added rapidly to the reaction mass. The reaction temperature rises to 0° C. The reaction mass is then poured into 500 ml anhydrous diethyl ether and a slurry results. The slurry is filtered under slight vacuum. The resulting filtrated is washed with three volumes of water followed by two volumes of saturated sodium chloride and is then dried and concentrated. The GLC profile for the reaction mass is set forth in FIG. 15.

The reaction mass is then distilled yielding the following fractions:
